In the practical use process, when the parallel wheel jumps, the suspension rigidity is consistent with the suspension rigidity change of the common stabilizer bar 1 system.

When the reverse wheel jumps, the suspension stiffness can be reduced in a small stroke (small-distance reverse wheel jump) to ensure the comfort of the automobile, and the suspension stiffness is increased in a large stroke (large-distance reverse wheel jump) to ensure the control effect of vehicle body side inclination, so that the suspension stiffness of the automobile can be changed in a certain time of the reverse wheel jump to ensure the comfort of the automobile, and the small-distance wheel jump and the large-distance wheel jump are distinguished.

The left wheel is used for explaining the convex process of the ground, and the specific working principle of the application is as follows: when passing through the bump, the left wheel jumps up and pulls the tail end of the stabilizer bar 1 to move upwards, at this time, for the common stabilizer bar 1 structure, because the stabilizer bar 1 is directly twisted under the constraint action, a larger suspension rigidity is generated to perform the vehicle body roll control, but the comfort of the vehicle is reduced, in the present application, because the gap 22 exists between the guide frame 5 and the bracket 2, the bracket 2 has a certain vertical free movement stroke on the guide frame 5 (see fig. 2), so when passing through the ground bump, the left stabilizer bar 1 moves upwards as a whole, and pulls the bracket 2 to move upwards together, because the upper end surface 23 of the lower part of the bracket 2 is not contacted with the top surface 21 in the guide frame 5, the stabilizer bar 1 does not twist in the upward movement stage, at this time, the stabilizer bar 1 does not generate the suspension rigidity basically, and at this time, the reverse wheel jump suspension rigidity is basically the same as the parallel wheel jump (see fig. 6 corresponding to "reverse wheel-present invention" (see the reverse wheel jump) Line drop change of (1); as the wheel hop increases (the stroke increases), the upper end surface 23 of the bottom of the bracket 2 contacts the top surface 21 of the inner space of the guide frame 5 (see fig. 3), and at this time, the bracket 2 cannot move upwards any more, so that the stabilizer bar 1 starts to be twisted, thereby generating suspension rigidity, and finally, the suspension rigidity of the wheel hop is increased remarkably and reaches the same suspension rigidity as that of the common stabilizer bar 1 (see the line rising change corresponding to "wheel hop-the utility model" in fig. 6); therefore, the suspension stiffness can be reduced in the small-stroke backward wheel jump to ensure the comfort of the automobile in a certain time, and the suspension stiffness is improved in the large-stroke backward wheel jump to ensure the roll control effect of the automobile body.

Specifically, please refer to fig. 6, wherein the line change corresponding to the "reverse wheel jump-the present invention" is the change of the suspension stiffness of the present application, wherein the concave portion of the line is the change of the suspension stiffness of the reverse wheel jump when the wheel passes through the ground protrusion, the falling portion of the line is the change of the suspension stiffness corresponding to the small-stroke wheel jump, at this time, the upper end surface 23 of the lower portion of the bracket 2 is not yet in contact with the inner top surface 21 of the guide frame 5, it can be seen that the lowest point of the suspension stiffness is close to the suspension stiffness of the parallel wheel jump, so that the comfort of the vehicle is ensured, after the lowest point, the suspension stiffness starts to rise, at this time, the upper end surface 23 of the lower portion of the bracket 2 starts to be in contact with the inner top surface 21 of the guide frame 5, the stabilizer bar 1 starts to be forced to twist, so that the suspension stiffness gradually increases, and finally reaches the same suspension stiffness as the common stabilizer bar 1, thereby ensuring the roll control effect of the vehicle body.

Any combination of the various embodiments of the present invention should be considered as disclosed in the present invention, unless the inventive concept is contrary to the present invention; within the scope of the technical idea of the utility model, any combination of various simple modifications and different embodiments of the technical solution without departing from the inventive idea of the present invention shall fall within the protection scope of the present invention.
